The robotic hand is made in a low polygonal density without losing quality on its surface, and this preparation in case you want to increase it, is natively made in Autodesk Maya 2018, which has two projects, one with all the settings and lighting of the scene to give results like the preview, and another scene without setting , later it was switched to c4d and adapted to the advance standard of cinema.
The model, despite not having rigin, but is organized in hierarchies and with its pivots positioned correctly so that an animation can be made despite not having riggin.
The textures are made in substance therefore they have an excellent 4k quality with their respective channels: -Diffuse -Roughness -Metallic -Height -Normal
